Exact and mean-field analysis of the role of Hubbard interactions on flux driven circular current in a quantum ring
Rahul Samanta, Santanu K. Maiti, Shreekantha Sil
We investigate circular current in both ordered and disordered Hubbard quantum rings threaded by magnetic flux, employing exact diagonalization and the Hartree-Fock mean-field appr…

Edge states and persistent current in a PT-symmetric extended Su-Schrieffer-Heeger model with generic boundary conditions
Supriyo Ghosh, Pijush K. Ghosh, Shreekantha Sil
We consider a generalization of the Su-Schrieffer-Heeger(SSH) model by including next-nearest neighbour(NNN) interaction and balanced loss-gain(BLG), and subjecting the whole syste…
